SEAT.

- application med April 14, 1922i. serial no. 552,676.

a resident of Pontiac, in the county of Oakland and State of Michigan, have invented certain new and useful Improvements in Seats, of which the following is a specilication.

This invention relates to a seat and more particularly to a seat structure for vehicles orthe like. l

The invention particularly relates to improvements over my Patent No. 1,406,059, bearing the date of Feb. 7 1922; and has for its object to provide a seat of the character specified, -in which all shocks to which the vehicle associated withtheesat may be subjected is absorbed, and thus at all timesinsure the comfortl of the occupant thereof.

In carrying out the invention itis conprising three units,'th e same being a seat boxing or housing, a seat back, and/the seat. The back is spring supported and adapted for free vertical movement and enclosed within the seat housing. The seat is supported by the back and also supported by supplemental springs to further absorb shocks to which the seat may be subjected.

The Vinvention is illustrated by Way of example in the accompanying drawings, in which Figure 1 is a erspective view of a seat construction of t e present invention.

Figure 2 is -a horizontal sectional view taken through the seat boxing or housing with the seat back positioned therein, and taken at a point immediately below the termina-tion of the upholstering of the seat back.

Figure .3 is a transverse sectional viewof the seat structure when fully assembled, as shown in Figure l.

Figure 4 Vis a perspective view of the seat unit.

Figure 5 is a transverse sectional view of the same.

Figure 6 is a horizontal sectional view taken substantially on the lines 6-6 of Figure 5.

preferably of the shape shown and comvthere is rotatably mounted a prising the rea'r wall 10, the two side walls 11, and the bottom 12. Also there should be provided along the forward edge of the bottom 12 an upwardly extending flange 13. Each free end of the side walls 11'is bent upon itself to form a casing 14 within which lthere is positioned a'fller or core 15. The

purpose of this construction will later become apparent.

Upon the inner side of the rear wall 1l of the seat housing there is secured a plurality of channel members 16, each channel member being spaced at its lower end from the wall 10 by a strip 16 in order that the channel members will be properly inclined. Also each side wall has 'secured upon its inner side a channel member 16 as shown. l/Vithin each channel member of both the side walls and also of the'rear wall rollers 17, said rollers, in each instance, be-

ing arranged in spaced relation longitu-l dinally -of the associated channel member 16 and preferably of the roller bearing type, as shown. l

The back B more particularly consists in a sheet metal body consisting of the black 18 and sides 19 which are formed substantially similar to the same portions of the `seat-ing the seat unit S in a'manner which will later be described.v Upon the rear face of the wall 18 of the seat back4 B there is secured a concave shaped strip 21 for each of the set of rollers 17, and a similar strip is secured to each side wall for the associated set of rollers 17.

Also adjacent the outer end of each side wall 19 there is secured aV channel member 22 and disposed in the manner shown. Each channel member 22 rotatably supports a plurality of rollers 23 which are of the ball bearing type and which engage with the casing 14 and form a stop against forward A plurality of movement of the seat back B. The seat back B is supported by a plurality of coil springs 24which rest upon the bottom 12 of the seat housing A. 'lhe forward face of thev seat back may have positioned thereon suitable upholsteringsgenerally indicated at 25.

IThe seat upon which there is supported a frame F through the means of the springs 27. The frame F consists in the two longitudinals consists in a base plate 26 i 28 and thecross members 29; and the springs 27 preferably engage beneath the longitudinals 28. A suitable iiexible covering 30 may extend over the frame F and have its sides and ends secured to the base plate 26 as shown. Upon the lcover 30 there may be positioned suitable stuiling 31 and the stuffing may in turnbe covered by leatheror the like as -at 32. The leather covering 32 should extend downwardly about the sides and ends which will eliminate any possibility of shock to the occupant thereof.

ofthe seat and have its lower edge secured to the base plate 26 as at 33. n y

Each cross member 29 of said frame F has its one side extended as at 34 an'd secured to this extended portion is a spring finger 35 which is in spaced relation with the extended portion 34. Also the forward longitudinal frame member 28 has its ends extended as at 35 and likewise has associated therewith a spring linger 36.

When assembling the present seat structure, the seat housing or boxing` A may be mounted in the vehicle in any desirable manner and then the seat back B may be positioned. This seat back isfreely removable from the seat boxing. After the seat back has been positioned then the seat S- may be placed inY position and the projections 34 of the cross members brought to engage upon the ledge 20 and likewise the projections 35 of the longitudinal frame member 28. The spring finger 35 associated with the extensions 34 andllikewise the spring fingers 36 associated with the extension 35 aid to hold the seat S in position. The seat `as "is apparent is freely removable as a unit.

The springs 24 in the arrangement of seat structure described' support the seat back B and also the seat S. rlhe seat S is further Lacasse subjected to a shock the back B is free to move upward and downward under the action of its supporting springs 24 and the seat S will be carried therewith Vlin case the shock is excessive the springs 27 of the seat S further absorb the same and it is believed that from this arrangement it may be obvious that l have provided 'a seat structure While li have shown and described the preferred form of my invention, I wish it to be understood that l am aware of the fact that the construction, combination and ai'- rangement of parts may be changed by those skilled in the art without departing from the spirit of the invention, as indicated bythe A.

appended claim.

l cla-im:

In a structure of the character described, a seat boxing, a seat structure within the seat boxing, spring for supportingA said seat structure for upward and downward movenient, said seat boxing consisting in sheet-vv metal and having a portionv at each y end thereof yturned upon itself to provide an elongated casing extending at right angles,

in each instance, to the associated side of the seat boxing, a reinforcing member in each of said casings, and roller vmeans carried by each associated end of the seat structure adapted to Aengage upon the inner walls of the casing and provide a4 stop to hold the seat structure against forward tilting movement.
